It does not spoil your happiness to confess your sin. The unhappiness is in not making the confession.
[Charles H. Spurgeon]

Proverbs 28:13 ... He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.
1 John 1:9 ... If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
2 Corinthians 7:10 ... For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death.
Psalm 32:5 ... I acknowledge my sin unto thee, and mine iniquity have I not hid. I said, I will confess my transgressions unto the Lord; and thou forgavest the iniquity of my sin. Selah. ❤
